Capabilities
CNC MACHININGWITH PROCESSES LIKE FORGING,CASTING, EXTRUSION, Our unique strength is in combining CNC machining with processes like custom steel forging, casting, extrusion, and surface treatment. This integrated approach enables us to deliver comprehensive supply chain solutions that surpass standard machining services by optimizing material usage, and ensuring superior quality and efficiency at every stage.
Precision Manufacturing Capabilities
One integrated partner for custom forging, die casting, sheet metal, stamping, CNC turning & milling, and wire EDM — every part built to your drawing, to your tolerance, to your specification.
One-Stop Integration
Raw material to finished part
Forging, casting, machining, stamping and finishing under a single quality system — fewer vendors, tighter traceability.
Precision
Up to ±0.005mm
CNC machining to ±0.01mm and wire EDM to ±0.005mm for your most demanding geometries.
Material Integrity
Full traceability
Certified alloys to your grade, sourced with full material certificates and in-process inspection.
Engineering Support
DFM from day one
Our engineers review every drawing for manufacturability to cut cost and lead time without compromise.
Forging & Die Casting
Custom Forging
Forge strength-critical components with controlled grain flow and near-net shapes that machining from bar stock alone can’t match.
- Closed-die & open-die forging in carbon / alloy steel, stainless, aluminum and titanium
- Optimized grain flow for higher fatigue strength and toughness
- Near-net shaping that cuts material waste and downstream machining time
- Integrated in-house CNC finish-machining and heat treatment
Changye advantage: Forging, CNC machining and surface treatment live under one roof, so your forged blank moves straight to finish-machining with no second vendor — tighter traceability, one quality system, faster turnaround.
Forging & Die Casting
Custom Die Casting
High-pressure die casting of complex, thin-wall aluminum, zinc and magnesium components at production volume.
- Aluminum, zinc & magnesium die casting with tight wall-thickness control
- In-house tooling design and maintenance for repeatable quality
- Complex geometries and integral features produced in a single shot
- Integrated CNC trimming, machining and surface finishing
Changye advantage: Our integrated line takes a casting from the die to a finished, inspection-ready part — no brokering multiple shops, no tolerance drift between vendors.
Fabrication
Sheet Metal Fabrication
Laser-cut, bent and welded sheet-metal enclosures and structures built precisely to your drawing.
- Fiber-laser cutting with clean edges and fine detail
- Precision CNC bending and forming
- TIG / MIG welding and mechanical assembly
- Integrated finishing: powder coat, anodize, plating
Changye advantage: One supplier handles cut, form, weld and finish, so your enclosure ships complete instead of bouncing between specialists.
Fabrication
Metal Stamping
High-volume progressive-die stamping for consistent, burr-free precision parts.
- Progressive and compound die stamping
- Fine-blanking for burr-free, net-shape features
- High repeatability across mass-production runs
- In-house tool and die shop for fast iteration
Changye advantage: Our in-house tooling keeps stamping economical and fast to iterate, while integrated machining handles any secondary operations your part needs.
CNC Precision Machining
Turning & Milling
Multi-axis CNC turning and milling for tight-tolerance, complex 3D components.
- CNC turning to ±0.01mm; Swiss-type for small, high-volume parts
- 3-, 4- and 5-axis milling for complex geometries
- Steel, stainless, aluminum, brass, titanium and exotic alloys
- CMM-verified accuracy with full material traceability
Changye advantage: Right process for the right part — we match turning, milling or multi-axis to your tolerance and volume, then finish in-house.
